apache tomcat集群Session 共享后报错！

经过这几天的网上查找资料。问题终于解决。原来是我在tomcat中server.xml中中的值设置错误。替换代码如下

 <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
    channelSendOptions="8">
    <Manager className="org.apache.catalina.ha.session.DeltaManager"
        expireSessionsOnShutdown="false" notifyListenersOnReplication="true" />
    <Channel className="org.apache.catalina.tribes.group.GroupChannel">
        <Membership className="org.apache.catalina.tribes.membership.McastService"
            address="228.0.0.10" port="45564" frequency="500" dropTime="3000" />
        <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
            address="auto" port="4000" autoBind="100" selectorTimeout="5000"
            maxThreads="6" />
        <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
            <Transport
                className="org.apache.catalina.tribes.transport.nio.PooledParallelSender" timeout="30000" />
        </Sender>
        <Interceptor
            className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector" />
            <Interceptor
            className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor" />
    </Channel>
    <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
        filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.css;.*\.txt;" />
    <ClusterListener
        className="org.apache.catalina.ha.session.ClusterSessionListener" />
</Cluster>

修改后启动。成功实现功能操作！
